Define as the development of new types of organisms from preexisting types of organisms over time
What is evolution
The three categories that provide evidence for evolution
What are comparative anatomy, molecular comparisons (DNA), and fossil records.
Explain what a cladogram is and what is shows.
A cladogram is a "tree of life" that shows evolutionary relationships between species or organisms. They can be used to show how recently species DIVERGED from common ancestors.
Who is the weirdest science teacher?
Mr. Harrington
The elimination of a species
What is Extinction
Defined as the study of locations of organisms around the world. Latin prefix for "life" and the word for study of location.
What is biogeography
What species is MOST CLOSELY related to Chimpanzees? How do you know?
a Mouse. It is the species that most RECENTLY shares a root on the cladogram with chimpanzees.
How much wood would a wood chuck chuck if a wood chuck could actually chuck wood?
700 lbs, actually. Its based on how much dirt a wood chuck can dig in a day.
Define "vestigial structure" and give an example in humans.
What is a structure that no longer has a purpose, but once did. appendix, coccyx, ear muscles, hair standing muscles, little toe, wisdom teeth, tonsils
Which Species on the cladogram ALL have Lungs?
Salamanders, Lizards, Pigeons, Mouse, and chimps
I appear 4 times in Mississippi, 1 time in Fire, but I never come in a second. What am I?
the letter I.
Evolution is an example of which type of science concept? Hypothesis, Theory, Law?
Theory
Define homologous structures and provide an example.
Structures found in different species that originated from a structure in a common ancestor of the 2 species. Bird wing/Human Arm/Whale Fin/Crocodile Arm/Cat Leg/Bat Wing
This evidence for evolution is called
Embryology
Hagfish are distantly related to modern day salamanders and lizards. What trait(s) separates Hagfish from both Salamanders and Lizards?
Jaws AND lungs
Remains of ancient species that have been preserved.
What is a fossil
Why do we say that individuals cannot evolve, only populations evolve?
An individual cannot change it's DNA significantly through the course of its life... but over many generations, their offspring can acquire new mutations and change drastically.
What does the "root" between Perches and Salamanders represent? Why is it important?
A "root" represents a COMMON ANCESTOR. its important because it shows that there was an INTERMEDIATE species that evolved into both of the modern day species.
Thus, we cannot say that Salamanders evolved from perches... They just share a common ancestor.
What is Mr. Johnston's favorite baseball team? Hint: Its in Southern California.
Los Angeles Dodgers
